Be it known that 1, Hammer: Famous, a citizen of the German Republic,and a resident of Hamburg Germany, have invented a new and useiulImproved Process for the Production of a Substance Resembiing Ebonite,of which the following is a specification. 4 1

gay invention concerns a process for the gr notion of an ebonite-likesubstancefrom lood, in which process the blood mixed with a bindingmedium or agglutinant such as -like substance of -,resin, an heated, ishardened with formaldehyde. As compared with the known process of kinthe present process is characterized by the circumstance that theproduct obtained on heating the blood with gum or v -resins, andsubsequently treating it with formaldehyde, is dried and ground,vwhereupon it is rendered plastic by the addition of a mixture ofcaustic alkali, and waterglass under ressure, in a This treatment is fort e urpose of giving to the final product, on t is one hand, therequisite elasticity, and on the other hand,

The process, illustrated by an example of execution, may be described asfollows:-

100 parts of fresh blood are mixed with about 5 of a 50 1: wnt solutionand heated to the boiling point. In place of tragacanth, other suitablesubstances, an as 1 -like substances or thelike,ma I'- I Then about onepart (if a- 402; formaldeh de solution is added. 4 e ca us formed ispressed in order to remove water therefrom as far as possible. Theresidue is dried by ap lication of heat and is then kenupand,sothatamofrethcius powder are mixed with to of a mixture consisting ofass or Later; glam, and caustic u mixture is for N me, u com f-suet, ,4,lnlopf water-glass, and 100 "7511596 caustic soda so ution.

t e powder has been carefully mixed with this solution, the productobtained is premed with the application of high and heat, where y apreparation is obtained which has approximately. the elastic ty anappearance of ebohite (or flame. dium,hard
